1 Claims. (01. 74-63) direction-and then m. the other direction, the re- This invention relates to mechanical movements and while it has a number of uses, it is particularly applicable where it is desired to have a one-to-one ratio between two revolving offset members, as,

1; for example, between a driving member and a driven member or between a relatively large diametered member and a small diameteredmemher in which, .for every revolution of the larger member, it is desired to have one revolution of the smaller member to maintain a predetermined relation between the members.

According to another aspect of my invention I propose to provide an improved irrevegrsible transmission, as will hereinafter be more ully pointed out, for ofiset members. For purposes of illustration I have shown my invention in very simple and more or less diagrammatic form in the accompanying drawing, wherein- Figure l is a partial section and side elevation illustrating the nature of my improvement.

' Figure 2 is an enlargedfragmentary view of certain portions of the apparatus, and

. Figure 3 is an end view of Figure 1 with the end plate removed and with the parts shown in a' position at right angles to that whch they have in Figure l. v

Referring now-to Figure 1, the reference numeral- -1 may be taken to be a driveshaft or other revoluble member with respect to which it is desired to have another'member rotate in a one-toone ratio; the reference numeral 8 may be taken to be any suitable means for imparting rotation, such as a gear wheel; and the reference numerals rotatable with the shaft 1 is a disk II which has parallel gear teeth l2 running in a direction across the face thereof.

,The reference numeral l3 'may be taken to indicafe a driven shaft having suitable beari gs l4 and having a yoke member 15 keyed to its nner end, the yoke member revolubly carrying agear wheel or gear roller IS the teeth of which mesh with the teeth I! ofthe disk II. The axes-of the shafts I and .13 are parallel but laterally displaced with respect to one another.

when the disk II is rotated in either direction it will be seen that the gear wheel or roller l6 will cause .the yoke 15 to revolve, the action being illustrated in the three figures. The shaft [8 will} of course, revolve with the yoke and the direction of revolution will be the same as that of the shaft 1. The gear wheel or roller 16, while imparting rotary movement to the yoke l about the axis. of

the shaft l3, revolvesat its own axis, first in one 9 and 10 any suitable bearings. Mounted on and" UNITED STATE FATE/NT OFF-ICE.

Ind Riverton,

versal taking place when the parts afein the position of Figure ,1, in which the axis of the gear wheel is at the horizontal.

As long as power is applied in either direction 5 I to the shaft 1, the shaft l3 will be caused to be rotated in a truly one-toeone ratio. As soon 'as the application of power to the shaft 1 is'cut oil and it is at rest, the parts remain'in position i for it will be seen that it is impossible to rotate 10 disk H from shaft iii. In other, words the arrangement is physically irreversible. This makes the device capable of a variety of applications. For example, it can be used in hoisting and lowering apparatus where it is desired to have parts remain in a given .position to which they have been moved Again it is useful in reeling mechanism such as cable reels. In fact the device may be used almost wherever it is customary to employ ratchet mechanism either single or double. Another use is in steering mechanism for automobiles. If the device is incorporated in steering mechanism it will be seen that in case of a blowout the reaction from the deflated tire cannot cause any shift from the running position of ad:

justment at the time of the blow-out. The operator, however, can still manipulate the steering wheel in the usual manner. It will be understood that I have indicated only a few of the uses to whichthe invention may 3 1 be put and that the drawing is to 'be takenas illustrating the general principle of the invention.- For example, the member l2 may be sta tionary and the plate I! rotated in which event a in every revolution of plate ll: the shaf t l3 will revolve once. Also the number of members I3 around the axis of rotationjmay be increased.

It will be apparent thatthe device is useful for setting controls as, for example airplane con- 0 trols and for retractible landing gears and any other places where the non-reversible characteristic. is desirable.

oluble plate member having parallel teeth} extendingover a face thereof, a power take of! shaft offset with respect to the plate, a gear member on the shaft meshing .with teeth of the plate, and means for mounting said gear member so to be 'revoluble on its own axis but otherwise rev-- I oluble as one with theshaft, said gear and mounting-means constituting means for transmitting rotative movement from the plate membet to the shaft in one to one ratio. vso

2. A mechanicalmovement including a pair of members one revoluble with respect to the other, parallel teeth extending across the face of one member, a power take off shaft mounted in .the other for rotation in an axis parallel to the axis of rotation of the revoluble member, and a gear wheel non-rotatably mounted on the shaft but rotatable on its own axis, said wheel meshing with said teeth.

3. A transmission device including a revoluble plate having parallel teeth across a face thereof, a gear wheel meshing therewith, a support providing an axis of rotation of the wheel in a plane parallel to the face of the plate, a power take off shaft on which said support is mounted, and a bearing for rotatably mounting said shaft with its axis extending in the same direction as the axis of rotation of the plate;

4. In a power transmission for effecting one to one drive, a revoluble plate having parallel teeth'extending across a face thereof, a gear wheel engaging said teeth, a yoke mounted for rotation on an axis extending in the same direction as the axis of rotation of the plate, means for rotatably mounting said gear wheel in the yoke, and a power take off shaft secured to said yoke axially thereof.

5. A mechanical movement comprising a plate having parallel teeth across a face thereof, bearing means for rotatably mounting said plate, a power take oil shaft, bearing means for rotatably mounting said shaft in parallel relation to the axis of rotation of the plate, a gear wheel, and bearing means carried by the shaft for rotatably mounting said gear wheel in mesh with the teeth of said plate.

6. A mechanical movement including a revooluble plate member having parallel serrations extending over a face thereof, a power take off 10 shaft having its axis extending in the same direction as the axis of rotation of the plate, and means movably mounted on the shaft and in engagement with the serrations of the plate, said means being movable along the said serrations l5 and effecting the transmission of rotative movement of the plate to the shaft in one to one ratio.
